Strong demand for mobile broadband equipment in Latin America will keep Ericsson's plant in Brazil at full capacity this year, says a senior executive at the telecom equipment manufacturer.

Mobile phone operators in Brazil are scrambling to improve their networks after heavy scrutiny from regulators because of poor service and a lack of investment in mobile infrastructure in recent years. The problems came despite a ballooning client base in Latin America's biggest economy.

But strong demand for faster, smartphone-friendly networks in neighboring countries is also fueling a growing need for mobile equipment elsewhere in the region.

"We see a growing demand in Latin America, both in 3G and 4G," said Andre Gildin, Ericsson's market intelligence director for the region, referring to the higher-speed networks that Brazil, Mexico, Colombia and other countries are rolling out.

The Swedish-based company expects 3G equipment to make up most of the demand this year in Brazil. Demand for 4G equipment is growing too as the industry begins building the country's fourth-generation mobile network.

The 4G effort is beginning in cities that in June will host soccer games during the Confederations Cup. The contest is a prelude to next year's World Cup, a much bigger event that is expected to strain Brazil's mobile telephone networks.

In 2012, about 40,000 pieces of mobile signal transmission equipment were produced at Ericsson's factory in the state of Sao Paulo. That took the factory to its production limit, a level that should be reached again by the end of the year.

"Our expectations are to finish this year with a similar number", Gildin said in an interview this week.

Half of this year's production will supply the Brazilian market, he added, while the rest would be exported to other Latin American countries. Big customers include operators in Mexico, which is implementing its 4G network, and Colombia, which is expanding both 4G and 3G services.

Argentina, Chile and Peru are also improving their mobile phone networks.

Ericsson (Stockholm, Sweden) says it has about 40 percent of the market in Brazil for 3G equipment. While the 3G network still has a long way to go in the country, the initial steps toward 4G services are helping the company get an early lead in that segment too, Gildin said.
